Molecular mechanisms: Rett, Angelman genes work together

by  /  13 August 2013

The genes involved in Rett and Angelman syndromes may collaborate to regulate the expression of other proteins, according to a study published 19 July in Biochemical and Biophysical Research Communications. This may explain the overlap in symptoms between the two disorders, the researchers say.

How can an experimental Angelman drug be so specific?

by  /  29 April 2013

A candidate drug for Angelman syndrome shows promise in activating the gene silenced in people with the disorder, and only that gene. Why doesn’t it unsilence other genes?

Stem cells reveal genes that have parental bias

by  /  31 October 2012

Researchers have used stem cells to identify 801 neuronal genes that are preferentially expressed from either the maternal or paternal chromosome, according to a study published 30 August in PLoS One. Of these genes, 26 are linked to autism and 48 to schizophrenia.
